The 1 invention relates to a toy which likewise appears as a'closedstructure when rotating, but

the configuration of which continually changes 4 owing to the shiftingof link chains and holding means. I g

' An embodiment of the invention is illustrated in the accompanyingdrawing in which:

Fig. 1 shows the toyin side elevation, the link 7 chain being omitted onone side. Fig. 2 shows a portion 0! the link chain in front elevation.

Fig. 3 is a top plan view of the shifting and holding plate. 1 I

A rack and pinion drive mechanism a with return spring adapted to beperiodically driven drives a shaft 21 carrying at its lower endashiftable plate d, the ends 0 of which are bent up? wards inclinedtowards the shaft and rolled inwards at their extremities. A plate 0'having 5 downwardly bent ends h with inwardly rolled extremities andcarrying an apertured disc I of adhesive material, such asrubber, isshiftably mounted on the upper end of shaft b. The ends c and h of theplates d and o are connected by chains formed ofbrightly painted sheetmetal links i-held together bywire links is. Byexert ing pressure on therack of the driving mecha-.-'

nism the shaft b and consequently the plates .12 and a and the chainsattached thereto gyrate, as the individual links of the chains beingthrown outwards by centrifugal force to form a configuration whichcan becontinually changed by shifting one or both of the plateso andd upwardsor downwards on the shaft b so that the chains are stretched orslackened and a larger \or smaller configuration will be formed, thewidth ofwhich is dependent upon the'mumber of links in the chains. Toenable larger and smaller conflgurations to'be; changed to? form othernovel configurations severaL bars or plates it having -apertures m forthe passage of the chain links and carrying each one an apertured rubberdisc 1 are'shiftably mounted cirthe shaft b. By shift- 80 shafttheconfiguration produced is again changed. Thus,.for example, with twoshiftable u p onthe end of thisspirel ww -which the plates aredisplaceable on said shaft :0

(CI. 46-47) q are suspended. 'If the shaft!) is rotated,the

toy figures will be swung outwards and describe a circle. At the sametime by varying the pressure exerted on the rack, the wire spiral willspread and contract so that the size of the circle describedby thefigures can be changed. p Withoutdepartingfromthe scope of the in-.vention large and small wires ,slidable on the .shaft and adaptedtoengage in eyes in the sheet v metal chain may be employed instead ofthe 10 plates n for changing the shape of the coniigura- 'tion producedduring the gyration. The links" of the chain may be made of othermaterial than sheet metal, and may beof different shape andinterconnected in a diflerent manner to that I} shown in the drawing.Finally, some other driving mechanism may beemployed in'steadpf a J rackand pinion-driving mechanism.

, adapted to rotate said shaft, bent over ends on said plates, andchains composed of separate links connecting said bent over ends andadapted 3 to swing out under centrifugal force during the rotationof"said shaft to simulate a,solid confi ration. 1
